OP'er here. I checked and no o-ring in the cap for the winterization port. I found one in my plumbing stash and installed it. I have the hose from the water tank disconnected and stuck into a bucket of water. The pump sucks the water out of the bucket just fine and the pump will build pressure and shut off just fine.
When I open the bathroom sink faucet it runs good for a few minutes then will start spitting again. It's not as bad as before the o-ring but it still spits. I have ordered a set of pex plumbing tools and will start replacing sections of the manifold. I am at a loss so that is my only recourse that I can see. Thanks to everyone who has responded. The encouragement is definitely a help.
Here is some pics of my water setup. All the fittings appear to be tight except one. It is behind that block of wood. I will replace the pipe and the clamps when my pex tools come in. Again thanks.

shadows4 - Have you tried running without the brass elbow in place?

I have the same brass elbow I use on my RV, I’ve found that I can’t leave it on the inlet with it capped as without the hose to clamp down on the twist head it doesn’t seal and leaks.

Bleed it starting at the highest point, usually the shower. make sure all other sources are closed when you start.

Are your setting valves just 90 degrees of turn? In other words, If you put a white mark on one end, can you turn the knob to get the white mark on the other end or 180 degrees of turn?
When I look at your top picture the diagram next to the knobs look like the knobs have a point on them but you have oval knobs. I'm thinking at least one of those knobs will turn 180 degrees meaning it is a three position valve. You would have to figure out which way they need to point and mark them for reference.

SUCCESS!!!!
I did find the air leak. I went to the hardware store and bought a fitting to plug into the end of the hose from the water tank. I then attached my blow out plug that I use for winterizing and applied 20psi of air pressure. I'll be darned if the leak was where I thought it was. In the last pic above it was behind the little block of wood.
So all in all I have $70 in a new water pump (thought originally that was the problem), and $80 in pex tools and clamps. I think it would have cost me more than $150 if I had to take it to a dealer. Thanks for all the replies and suggestions. You all are awesome!! Thanks again.

This is how I hooked up the air from my little compressor.
